The issue was tracked down to the hash of an endpoint inside a boost::multi_index_container being different depending on where it was called. Unfortunately it seemed that it was only easily reproducible on a release configuration on Windows which made debugging a bit harder. The culprit was the ip_address_hash_raw function which assumes that the same random constants variable is used each time. This is the case in the same translation unit, but because it is defined inside an unnamed namespace in a header, each translation unit which includes this (common.hpp) gets its own copy and hence each initialises its own static random_constants. Why it is a problem for some compilers/configurations and not others probably boils down to some compiler specific optimisations.
